Count Dracula [Christopher Lee] lies in a stone chamber high inside his castle, his remains resting on a cold plinth while a narrow window offers the only glimpse of the outside world. A large bat circles the chamber, skimming the air and finally regurgitating blood onto the Count’s lifeless form. In that dark moment, the blood itself seems to stir, and the once-sleeping corpse begins to wake. The transformation is swift, and the ancient vampire is reborn, reasserting his presence with a quiet, predatory calm that unsettles anyone who witnesses it.
The village below soon learns that the nightmare has begun anew. The Count’s brutality continues, and a wave of fear sweeps through the locals as another young woman is found slain, the violence blamed squarely on the living legend. In the aftermath, a priest’s blessing is sought, and the villagers muster their resolve to confront the threat. They gather courage and march toward Dracula’s castle, setting the fortress ablaze in a fiery bid to end the bloodthirsty reign. Yet while the flames lick the walls, the Count remains hidden in his solid stone chamber, seemingly untouched by the destruction outside. When the smoke clears, the villagers discover a darker reality: upon returning to their homes, they confront the shocking sight of every woman in the village murdered inside the church by a swarm of bat-like creatures—a chilling reminder that the menace has not only endured but metastasized.
Meanwhile, far from the uproar in the hills, the story follows a libertine named Paul Carlson [Dennis Waterman], who finds himself falsely accused of a grave crime. He flees the Kleinenberg authorities by leaping into a coach of his own making, a driverless vehicle that speeds him toward the border. After breaking through the border guard’s scrutiny, Paul is knocked from the coach and stumbles into a nearby inn, where the waitress Julia [Wendy Hamilton] extends a cautious welcome. The inn’s keeper disrupts the moment, sending Paul back to the cold night and into a forested path where he stumbles upon the driverless coach again—and discovers that it is now in the hands of Klove [Patrick Troughton], Dracula’s devoted servant, who drives it back toward the castle.
Inside the castle, Paul is first met with a measure of hospitality from the Count himself and from Tania [Anouska Hempel], a woman who soon reveals that she is Dracula’s prisoner and mistress. The two share a fateful liaison, but the moment of intimacy ends in horror as Dracula confronts them. He seizes control, and, in a stark moment of betrayal, stabs Tania through the heart to punish her for betraying him. He wastes no time in feeding from her dead body, while Klove dismembers Tania’s body and dissolves the remnants in a bath of acid. Trapped in a room high in the castle, Paul attempts to escape by using a rope of bed curtains to reach a lower window, but the line is suddenly withdrawn by Klove, and he finds himself back in Dracula’s inner chamber.
Paul’s elder brother, Simon Carlson [Dennis Waterman], along with Simon’s fiancée Sarah Framsen [Jenny Hanley], set out to find him. A tavern maid guides them to the castle, where Dracula casts his gaze on Sarah, but Klove—who has secretly fallen for her after seeing her photograph among Paul’s belongings—chooses not to obey Dracula’s will and helps the couple escape by sparing Sarah’s crucifix. For this defiance, Klove is punished by Dracula with a red-hot cutlass burn, a stark reminder of the vampire lord’s iron control. The priest is killed by a vampire bat during the ordeal, and Simon’s trust is tested as Klove secretly betrays him as well, leaving him trapped in the same windowless, doorless chamber that held Paul.
Simon’s discovery inside the room is shocking: the coffin in the center holds the sleeping Dracula, and the Count’s presence is so overwhelming that the human senses are overwhelmed as the vampire’s powers seem to seep through closed eyelids, causing Simon to collapse before he can act. When at last Simon recovers his senses, Dracula has vanished from the room, leaving behind a disturbing scene: Paul’s lifeless body now skewered on a spike, a grim trophy of the Count’s iron rule.
Outside, Dracula climbs the castle walls with unsettling speed, slipping along the surface as if he were a creature smaller than a man, almost insect-like in his motion. Seeing the Count on the battlements above, Simon calls out as a rope is lowered and he begins a dangerous ascent to reach Sarah—who has, in the meantime, made her way to the castle’s outer edge as a storm rumbles ominously in the distance. Dracula arrives on the battlements and uses his bat familiar to strip Sarah of her crucifix, but Klove returns in time to confront the Count. A brutal struggle follows, and the servant is flung over the side to his death as the storm intensifies.
The climactic confrontation reaches its peak when Simon, now on the scene, snatches a loose metal spike from the battlements and hurls it at Dracula. The spike penetrates the Count’s lower torso, missing his heart but delivering a grave wound. Dracula, undeterred by the attack, lashes out toward Simon, threatening to impale him with the same spike. A blinding flash of lightning travels across the sky, and a sudden burst of fire engulfs the vampire in a blaze of electricity and flame. Dragged by the storm’s force and weighed down by his injuries, Dracula collapses from the battlements and plunges to the ground far below, where his body continues to burn as the castle and its dark legacy begin to crumble.
